Some of the characteristics of the drive plate 

 The use of professional audio VU driver IC , not our past with TA7318, this IC includes dynamic root compression circuit, logarithmic output characteristics, small signal pointer does not move to avoid large signal when the pointer bottoming The phenomenon.

 The IC has a mute function, in the boot of the moment, the mute function will be a low-level foot, so to avoid the instantaneous power, rendering the pointer about the phenomenon. In line with the boot of the habit, the pointer will have a small swing swing.

 The circuit AC12V power supply, rather than TA7318 the minimum DC20V power or more,use original IC BA6138  use will be very convenient.

 The double-sided circuit boards, in fact, in order to ensure pressure line terminal firmly, will not after repeated wiring, terminal pads for loose possible.

 Each one driver board, we have been specialized test stand test and adjusted to ensure consistency of quality

 

Driving board design layout is beautiful and reasonable, there is no interference and self-excited phenomenon

 

Wiring card:  each plate, are equipped with a beautifully printed wiring instructions card, according to the outlet header, the correct wiring, if pick the wrong line, there is danger of burning the table.

Each board, we have been specialized test stand for testing and calibration, no special requirements, we are all input 1W / 8 Euro ( 2.83V ) , with a P-55 table header to do a load test, the pointer is swing 0DB scale. If there are special requirements, can be text messages. Swing adjustment, in addition to adjust the load potentiometer, in fact, can also be considered from the input voltage divider circuit.

     LED backlight brightness, adjustable R9 and R10 resistance is achieved, with the backlight electrical parameters, according to Ohm's law can easily be calculated, and if you want to help, please message us like, or send Mail to:Carloamp@ampmart.com

Crimping terminal

   We choose the pressure line terminals, a high degree of moderate, the most critical is that the way pressure line is very reasonable, can be very firmly compacted the size of the line size of the line. In addition, we use the double-sided, pressure-line terminal pad is relatively strong, not easy to loose. 

Board size

    Circuit board mounting dimensions, the frame is 67.4MM * 56MM installation size, screw holes: 57MM * 50.5mm . Screws fit with M3 screws. 

Please note:

      The IC model used in this circuit has been polished, please consider before buying, the cost of the board factory 100% tested when the normal use of the case does not happen
